Seven species of parasites were recovered from the puparia ofOscinella frit(L.) over a three-year period at Blacksburg, Virginia. They were:Spalangia drosophilaeAshmead (Pteromalidae),Hexacola hexatoma(Hartig) (Cynipidae),Bubekia fallaxGahan (Pteromalidae),Trichomalus statutus(Foerster) (pteromalidae),Callitula bicolor(Spinola) (Pteromalidae),Halticoptera aenea(Walker) (Pteromalidae), andHorismenus texanus(Girault) (Eulophidae).H. hexatomaandT. statutuswere new North American records:O. fritwas apparently a new host record forB. fallaxandH. texanus. The parasitism rate was generally low in each of the three generations ofO. frit. Either the parasites were not strongly oriented to the frit fly, or they were not well adapted to its environment, as none of the parasites were collected during each year of the study
